This backlight strip is designed for screens, offering high brightness, energy efficiency, and environmental protection. Featuring closely spaced LED particles with a high-density arrangement, these imported highlight LED strips provide excellent performance and long service life, lasting up to 100,000 hours. Easy to install using double-sided adhesive, the strip can be attached to the original LCD groove or other desired locations. Installation guidance: - If your monitor uses an inverter, this kit replaces the inverter and connects directly to the driver board. - If your monitor has a high-voltage integrated power supply board, disconnect the original connection. Identify the 12V (capacitance) using a multimeter. The board receives three lines: 12V, ON, and GND. Connect the 12V from the inverter to the 12V positive terminal on the high-voltage integrated power supply board, GND to the negative terminal, and ON to the ON/OFF signal. In summary, the original high-voltage power supply connection is removed and replaced with the inverter, drawing power from the original source.
